Title: Improvements in or relating to cartoning machines
IPC: B65B5/02
Filed: 1946-08-26
Abstract: 615,100. Filling and closing cartons. MACKENZIE, W. E., and OXO, Ltd. Aug. 26, 1946, No. 25452. [Class 94 (i)] A cartoning machine in which the article to be wrapped is advanced against the carton blank while contained within the lower end of a chute through which the article is delivered and which comprises side walls corresponding in shape to the shape of the articles, means being provided for folding the walls of the carton around the lower end of the chute, means for withdrawing the chute from the carton and for retaining the article in the latter and further means for completely folding the carton to cover the remaining face of the article,. A carton blank for wrapping an article in the form of a cube is fed to a carrier 10 by means of a punch 6 which feeds the blank through a die 5, Fig. 3, which shapes the blank, as shown in Fig. 2, to form trough-like portions for embracing two opposite side walls of the article to be wrapped. Each blank comprises two relatively narrow strips 7 and 8 disposed at right angles in the form of a cross, the trough-like portions 7 being disposed, one on each side of strip 8. The carrier is moved and disposed below a chute 1, Fig. 6, which delivers an article on to the blank, the sides and ends of which are folded about the lower end of the chute by folding blades 11 associated with the carrier. Means are provided to remove the chute from the carton, the article being retained in the carton by the pressure of plunger 3. The carrier is then moved to a position in which two wiping elements 12, Figs. 8 and 9 turn the outer ends 7a of the carton over the top face of the article. On withdrawal of wiping elements 12, a third wiping element 13 which folds over end tongue 14, a fourth wiping element folding over the remaining tongue 16 simultaneously with the withdrawal of element 13. A heating element may be provided to contact an adhesive, applied to the last-mentioned strip, which becomes tacky on the application of heat, to seal this tongue to the part of the carton below it. The completed carton may then pass under a cooling plate which contacts and cools the just heated part of the carton. The various steps of the operation take place during the intermittent rotation of a rotor on which the carrier is mounted and which brings the carrier successively into positions opposite stages for effecting each particular step.

Title: Improvements in or relating to rolling machines of the bridge type for the treatmentof leather
IPC: C14B1/30
Filed: 1949-10-12
Abstract: 661,532. Leather-rolling machines. SVIT NARODNI PODNIK. Oct. 12, 1949 [Oct. 30, 1948], No. 26179/49. Class 76. A rolling machine of the bridge type having a reciprocating working roll the direction of movement of which is changed by means of a shifting rod provided with stops which limit the working path of the roll, is characterized in that the shifting rod has fixed stops which are disposed along two opposite helices as viewed from the centre point of the said rod. As shown, a slide 4 with working roll 5 is suspended from an overhead beam 3 and is moved to and fro by a screw-threaded spindle 6 driven by a motor 7 through the intermediary of a bottom countershaft 8 and top countershaft 9, a straight belt 10, a crossed belt 11 and wedge-shaped belts 12. Belts 10 and 11 idle on loose pulleys 13 and 14 and may be moved on to the fast pulley 15 (thus determining the movement and direction of rotation of the spindle 6) by means of the belt fork 16, shifting link 17, lever 18 and shifting rod 19. Fixed stops 20 are provided on, and are integral with, the shifting rod 19 and are arranged to form opposed helices as viewed from the centre point of the shifting rod 19 (Figs. 2 and 2, not shown). The slide 4 carries two spring- urged contact elements 21 which, when engaged with the positioned stops 20, produce longitudinal movement of the shifting rod 19 and thereby reversal of the operation of the machine. The shifting rod 19 is mounted on bearings 22 at the rear of the machine and is connected to a hand-operated control rod 25 at the front of the machine and parallel thereto through the intermediary of a chain transmission gear. In operation, the operating stroke of the working roll 5 is adjusted by turning the control rod 25 about its longitudinal axis to position a corresponding pair of stops 20 on the shifting rod 19 opposite the contact elements 21 of the slide 4. The stops are grouped on both sides of the centre point of the shifting rod into helices in such a way that the two corresponding opposite stops nearest to each other serve to limit the shortest working stroke of the roll, while the two stops which are most remote from each other serve to limit the largest working stroke of the roll.

Abstract: 1,007,959. Automatic exchange systems. SIEMENS & HALSKE A.G. July 3, 1963 [July 4, 1962], No. 26324/63. Heading H4K. Apparatus for testing the idle or busy condition of a circuit is enabled to distinguishbetween an idle circuit and one that is just releasing after use. The circuit under test is represented as shown by a resistor R in series with a relay C of which winding II is normally short-circuited. When the circuit is seized by a selector W, relay C energizes over coil Dr and resistor R1 and inserts winding II. When the circuit being tested is in an idle condition, the potential at x rises rapidly, operating transistor T1 and blocking T2. The potential at a falls and operates through a differentiating circuit C3, R15 to switch a trigger pair T3, T4. Relay P energizes and applies a busy potential. If however the circuit is releasing, winding II of C being not yet short-circuited, the potential at x rises slowly on account of the higher inductance of C, and the slow fall of potential at a does not affect the trigger pair T3, T4 through the differentiating circuit on account of a Zener diode D3.

Title: Process for the separation of oily or fatty substances and the like from liquids containing the same
IPC: C11B11/00
Filed: 1923-10-23
Abstract: In the separation of oils, fats, and waxes from emulsions by froth flotation a satisfactory froth is obtained by cooling the froth, and regulating the temperature of the liquid, the amount of air introduced, the fineness of the bubbles, the depth of the liquid and of the froth, the tranquility of the surfaces of contact of the liquid and the froth, and the draining and washing of the froth for the removal of adhering liquid.  The temperature preferred is usually just above the melting-point of a fat or wax. In the separation of wool fat the scouring liquor is cooled to 90-100 DEG  F. and is passed through one or a series of boxes in which it is kept at a depth of about 1 ft., and about 200 volumes of air are forced through a cloth or canvas base.  The froth is washed continuously with fine sprays of cold water, and after it has reached a depth of about 2 ft. it is removed continuously or in batches.  The sprays may be used to make the froth spongy; such a froth may be accumulated to any depth. The froth removed is broken and washed by sprays of cold water, and the separated wool fat dried by heat.  The treated liquor is re-used for scouring, preferably after settling to separate sludge.  Other applications specified are the separation of mineral lubricating oil from water, and the treatment of milk to separate the fat or butter.
